Therefore, the research on how to treat the surface roughness of the inner wall of the titanium pipe has very important significance for controlling the expansion joint quality of the titanium pipe.

step 2), a polishing wheel (8) of the small-diameter titanium tube inner wall polishing device stretches into the titanium tube, and the polishing wheel is pulled back and forth at a constant speed along the length direction of the titanium tube after a motor switch is started;
Step 3) taking out the small-diameter titanium tube inner wall polishing device from the titanium tube;
and 4) after finishing the polishing, performing polishing degree inspection on the inner wall of the titanium tube.
8. The method for polishing the inner wall of the titanium tube according to claim 7, wherein in the step 2), a polishing wheel (8) of the small-diameter titanium tube inner wall polishing device is extended into the titanium tube, and is pulled back for 3-4 times at a constant speed along the length direction of the titanium tube after a motor switch is started, and the polishing roughness Ra is less than or equal to 0.8 mu m.
9. The method of claim 8, wherein the step 4) of inspecting the degree of polishing comprises inspecting using a high-intensity torch, a depth gauge, and a roughness reference block.
